Description

Dow Corning Architectural Insulation Modules are fumed silica cores contained in layers of polyethylene, polyester, and aluminum. The panels are available in a variety of widths and lengths up to 2' x 4' and range in depths from 0.25"–1.5". The panels achieve an unusually high insulation value, although due to thermal bridgingHeat flow that occurs across more conductive components in an otherwise well-insulated material, resulting in disproportionately significant heat loss. For example, steel studs in an insulated wall dramatically reduce the overall energy performance of the wall, because of thermal bridging through the steel.

changes considerably depending on the size of the panel. Standard 2' x 4' panels achieve R-30 per inch, and even if the vacuum is lost, due to edge seal failure or accidental puncture, still maintain R-8 per inch, due to the fumed silica core. The panels can be installed in many different applications, including historical retrofits, underneath rainscreenConstruction detail appropriate for all but the driest climates to prevent moisture entry and to extend the life of siding and sheathing materials; most commonly produced by installing thin strapping to hold the siding away from the sheathing by a quarter-inch to three-quarters of an inch.

, and in curtainwall spandrels. To protect against accidental loss of vacuum, various strategies for protecting the panels have been developed. The panels cost significantly more than conventional insulation.
